“…were positively influenced by NO 3 -N, PO 4 -P, and organic matter. A similar study was carried out by Sharmin et al [71] where they found that several environmental parameters namely temperature, depth, pH, soil organic matter, and soil organic carbon reflected a close relationship with Mollusca and Annelida therefore, less association were observed with Arthropods.…”

Macro-benthos is commonly considered an indicator for evaluating the health of an aquatic ecosystem. Earlier research from sub-tropical mangrove estuaries, however, has primarily relied on conventional taxonomic methods to determine the pattern of macro-benthos diversity. Therefore, this study aimed to describe the pattern of both taxonomic and functional groups of macro-benthos with respect to ecological variables in three separate seasons (pre-monsoon, monsoon, and post-monsoon) from a mangrove-dominated Pasur River estuary, Bangladesh. The findings revealed significant seasonal variations in the water and sediment parameters (p < 0.05). During the study period, 47 species belonging to 35 families of macro-benthos were identified. The pollution indicator species, Capitella capitata complex was found to be dominant. The highest density of macro-benthos was recorded in post-monsoon (545 ± 13.76 ind./m2) followed by pre-monsoon (214 ± 5.57 ind./m2) and monsoon (63 ± 2.27 ind./m2). Diversity indices, Shannon, and evenness also displayed a similar seasonal trend. This pattern may be explained by the more stable bottom and higher food availability during post-monsoon, and on the other side, by erosion and higher turbidity during monsoon. Analysis of similarity (ANOSIM) detected a significant difference in community assemblage among the seasons (R = 0.7222, p = 0.0005), whereas similarity percentage analysis (SIMPER) identified Dendronereis aestuarina as the most contributory species for the overall average dissimilarity. Six functional feeding groups (FFGs) were identified where gathering collectors (GC) had the highest total density (221.83 ind./m2) and relative abundance (26.97%). The community was shown to be shaped by the amount of sedimentary silt and dissolved oxygen in the water main, according to a canonical correspondence analysis (CCA) study, they were positively correlated with the abundance of Pristinella acuminata, Lumbrineris sp., Cossura coasta, C. capitata complex, Neritina violacea, Laccotrephes griseus, Hydrometra butleri, Gomphus sp. and Libellula sp. CCA analysis also revealed a significant positive influence of pH, NO3-N, PO4-P, and organic matter, whereas, sand particles of sediments were found to have a negative effect on FFGs. Overall, the study suggests that the estuary is moderately diverse with macro-benthos and their functional feeding groups and influenced by monsoon strongly. The present study on FFGs of macro-benthos in an estuarine river of Bangladesh will provide baseline information for further investigation of other estuaries.

This study was conducted to compare mollusc diversity in migratory bird visiting and non-visiting lakes of Jahangirnagar University campus, Savar, Bangladesh from July, 2016 to June, 2017. A total of 13 species belonging to 6 families under 2 classes of Mollusca were encountered. The class Gastropoda dominated the faunal composition (91%) with 11 species under 5 families and the class Bivalvia constituting (9%) with 2 species under single family. Among them Bellamya bengalensis, Lymnaea accuminata, Indoplnorbis exeutus, Gyraulus convexiusculus, Melanoides tuberculata and Lamellidens marginalis were the most dominating taxa. The highest number of molluscan taxa was from the family Viviparidae (3 spp.) 29% followed by Planorbidae (2 spp.) 27%, Lymnaedae (3 spp.) 23%, Unionidae (2 spp.) 9%, Thiaridae (1 sp.) 8% and lowest from Piladae (2 spp.) 4%. Seasonal variation showed maximum density in the summer and minimum in the monsoon. Correlation (p> 0.05) indicate that B. bengalensis, L. accuminata, I. exustus, L. marginalis had close dependency to soil pH, soil organic Carbon, Soil organic matter and sand particle whereas M. tuberculata and G. convexiusculus show significant positive correlation with silt and clay particle. Biodiversity indices indicating low species diversity and richness of molluscs in both migratory bird visiting and non-visiting lakes. These findings emphasized the importance of protection and management of molluscs fauna in the lakes for supporting the food for the migratory birds. Bangladesh J. Zool. 47(2): 355-366, 2019

“…The contribution of soil organic carbon and total chlorophyll was also found to be significant during the whole study. According to [24], soil organic carbon influences the distribution pattern and abundance of the benthic species especially annelids and molluscan groups. The correlation between soil organic carbon and dragonfly nymph showed a significant 'r' value of 0.518, p < 0.05.…”

Freshwater riverine systems are facing series of stress due to different anthropogenic activities, eutrophication and geomorphological alterations. Pollution is the current ecological hazard leading to the deterioration in river water quality and thereby modifying the quantitative distribution of the inhabiting organisms. In the present study, four major eco-physicochemical parameters are selected to correlate with the available benthic species distributed in the entire stretch of river Ganga, India. Total nitrogen, total phosphate, total chlorophyll and soil organic carbon are considered to be the primary indicators of water and soil pollution and hence, contemplated for correlation with benthic distribution. Out of the total recorded 69 species from river Ganga, 13 species belonging to three different phyla viz. Mollusca, Arthropoda and Annelida was observed to be influenced (p ≤ 0.05) by the aforesaid pollution indicating parameters. Among those 13 species, four species belong to class -Gastropod (Physella acuta and Mekongia crassa) and class -Bivalvia (Parreysia corrugata and Indonaia andersoniana); seven species belong to class Insecta (Anax sp. Dragonfly Nymph, Notonecta sp., Caenis sp., Rhyacophila sp., Philopotamus sp. and Chironomus larvae); and two species belong to class Clitellata (Tubifex tubifex and Lumbriculus variegatus). The strong negative correlation of Mekongia crassa with total phosphate indicated that the species can be marked as an essential aquatic riverine indicator species. The present study can conclude that these identified benthic species can be used as bioindicator organisms for pollution monitoring and riverine health.
